PENDANT WINDING AND'SETTING WATCH.-

SPECIFICATION forming part of Letters Patent No. 357,906, dated February15, 1887.

Application filed August 29, 1885. Serial No.175,620. (No model.)

To aZZ whom it may concern.-

Be it known that I, DUANE H. CHURCH, of Newton, in the county ofMiddleseX and State of Massachusetts, have invented certain new anduseful Improvements in Pendant WVindin g and Setting Watches, of whichthe following is a specification. V

This invention relates to stem winding and setting watches in which theswinging yoke carrying the pinions, which respectively communicatemotion from the crown-wheel, actuated by the rotation of thewinding-stem, to the mainspring-barrel in winding, and. to. the dialtrain in setting the hands, is normally held in its winding position bya spring, and is moved to its hands-setting position against the stressof said spring by a longitudinal movement of the winding-stem.

The object of this invention is to provide simple and effective meanswhereby an outward endwise movement of the winding-stem is caused tomove the yoke from its winding to its hands-setting position; and tothis end it consists in the combination, with the yoke and thewinding-stem, of a pivoted arm or lever engaged with the winding-stem,so as to be oscillated on its pivot by the inward and outward endw-isemovementsof said stem, and

a stud or pin on the yoke bearing againstsaid lever, the arrangementbeing such that an outw ward lengthwise movement of the windingstem Willcause the lever to swing on its pivot, and by its contact with the studon the yoke move the latter to its hands-setting position, the leverbeing so moved by the inward movement of the winding-stem as to releasethe yoke and permit its spring to restore it to its winding position,all of which I will now proceed to describe.

Of the accompanying drawings, forming a part of this specification,Figures 1 and 2 represent, respectively, front and rear views of aportion of the pillar-plate of a watch-movement provided with myimprovement, the yokebeing shown in its hands-setting position. Figs. 3and 4 represent similar views showing the yokein its winding position.Fig. 5 represents a longitudinal section through a part of thewinding-stem, top plate, and pillar-plate, showing the means for holdingthe inner end of the winding stem stationary while the main portion ofsaid stem is being secured to it.

In the drawings, a represents the yoke, which is pivoted to thepillar-plate b, as usual, and carries at one endthe pinion e and at theother end the pinion f, said pinions meshing with the crown-wheel g,which is rotated by the winding-pinion i, the pinion e meshing also withthe main wheel j on the mainspring-barrel or arbor when the yoke is inits winding position, Figs. 3 and 4., while the pinion f meshes with oneof the wheels of the dial-train when the yoke is initshands-settingposition, Figs. 1 and 2.

The winding-stemkis adapted to slidelengthwise in its winding-pinion,and has a square port-ion fitting a square socket in the windingpinion.

Z represents a lever pivoted at m to the pillar-plate b, and having anotch or recess, a, at

one side ofits pivot, receiving a flange, 0, on

an extension or tip, k, secured to the windingstem k. At the oppositeside of the lever Z is an extension, which is provided with two edges, 23, adapted to bear alternately against a stud affixed to the yoke, theedge 3 bearing against said stud when the yoke is in its handssettingposition, and the cdge2 when the yoke is in its winding position.

Then the yoke is in its winding position,the winding-stem is movedinwardly,and the stud q bears upon the edge 2, as shown in Fig. 4,theyoke being normally held in said position by the usual spring, r. Whenthe Winding-stem is moved outwardly, the engagement of the flange 0 withthe lever Z causes the latter to turn on its pivot to the position shownin Fig. 2, and thereby move the yoke to its hands-setting position, andprevents the spring 1' from moving the yoke back to its normal positionuntil released by the inward movement of the winding-stem.

The tip it, having the flange 0, is provided at one end with a threadedsocket, into which the reduced end of the winding-stem is screwed afterthe tip has been inserted in the socket s .9, prepared for it in thepillar and top plates of the movement. (See Fig. 5.) The tip isprevented from rotating when the winding-stem is being screwed into itby ascrew, t, inserted in the top plate, a, said screw being turneduntil it bears firmly against the flange 0, so as to hold the toprigidly. After the winding stein has been screwed in the screw t isloosened, and the windingstem and tip are thus enabled to rotate andmove freely lengthwise.

It will be seen that the described devices constituting my improvementare simple, efficient, and durable.

Other equally obvious modifications may be made without departing fromthe spirit of my invention.

I claim- The'oombination, with the hand setting and winding mechanism,of a spring-pressed yoke having a stud, q, the pinions carried by saidDUANE H. CHURCH.
